Abstract: Portulaca oleracea has been used throughout history for many different medicinal purposes. This invention is directed to the novel use of P. oleracea for the treatment of cancer. More specifically it is disclosed that P. oleracea has a specific and distinct effect on the inhibition and/or suppression of gastric tumor cell growth in vitro and in vivo. An aqueous extract of P. oleracea showed a tumoricidal activity against KATO III (human gastric carcinoma cell line) and COLO 320 HSR cells (human colon adenoma cell line) in a dose-dependent and time-dependent manner, but not against the non-tumorous cell lines, L929 (murine lung connective tissue) and WI38 (human lung diploid cell) cells. Subcutaneous injection of six week old CD1nude mice with COLO 320 HSR cells and subsequently Portulaca oleracea extract showed a clear inhibition of tumor growth as compared to the control nude mice which received only COLO 320 HSR cells.

Granted: 2001-02-06
Abstract: An apparatus and a method for completing long distance telephone calls over the Public Switched Telephone Network (PSTN) using an automated Internet Operator are disclosed. The apparatus includes a long distance service provider node connected to the Internet and a call connection control computer connected to the Internet and interfaced to a toll switch connected to the PSTN. The method permits a calling party to request the automated Internet Operator to complete long distance call connections by connecting to the long distance service provider node and identifying himself. The caller completes a call request form which is uploaded to the long distance service provider node and passed to the call connection control computer for processing. The call connection control computer instructs the toll switch to dial the calling party, dial the called party and conference the two lines. The call connection control computer preferably uses a least cost routing algorithm to select an interexchange carrier for each call, depending on the origination and termination location of the call. The advantage is a flexible long distance service that is not interexchange carrier dependent for the best long distance rates.

Abstract: l'invention concerne un système d'entraînement hydraulique (2) pour un véhicule comportant un circuit de mise en pression (5, 5'') et un circuit de travail (7, 7', 7'', 7...). Une pompe (11), mue par un machine motrice (20) ayant une puissance nominale en cheval-vapeur, est incorporée au circuit de mise en pression. Cette machine motrice, qui est coupée ou bien tourne au ralenti lorsque la pression détectée dans le circuit de mise en pression se trouve à l'intérieur d'une plage souhaitée, fonctionne dans une plage optimale de régime élevé lorsque la pression tombe en dessous de la plage souhaitée. Le circuit de mise en pression, qui comporte également au moins un accumulateur (29), est pourvu de plusieurs moteurs (107, 108, 128, 129; 606-609; 651-654; 687a-692b), destinés à entraîner au moins une roue de véhicule, ainsi que d'un agencement de soupapes régulatrices (97, 133, 134; 621-624; 666-669; 710-716) qui isolent un ou plusieurs moteurs du débit de fluide sous pression lorsqu'elles sont désactivées et entraînent les moteurs lorsqu'elles sont activées. Au fur et à mesure que s'accroît la vitesse du véhicule et que décroît la résistance à l'entraînement, le nombre de moteurs propulsant le véhicule diminue progressivement. Une soupape régulatrice modifie le débit du fluide vers les moteurs.

Abstract: A method of manufacturing a porous electrode wire for electric discharge machining, comprising passing a wire rod comprising a first metal containing copper through a plating bath of a second metal having a vaporizing temperature lower than that of the first metal to form on a surface of the wire rod an alloy layer having a hardness higher than those of the first and second metals and an elongation percentage lower than those thereof by a diffusion reaction of the first and second metals, forming a layer of a plating metal comprising the second metal on a surface of the alloy layer, and then drawing the resultant wire rod to form cracks in the alloy layer and the plating metal layer. This electrode wire has an improved working rate at least 15 % higher than that of a regular zinc-plated electrode wire and such an improvement of the working rate is ascribed to an increase in the surface area of the electrode wire owing to a porous structure of the surface thereof which in turn increases a rate of cooling the electrode wire with a working fluid.

Abstract: A dual function, inboard barrier/bridgeplate assembly for wheelchair lifts having a stowable platform, the barrier being pivotably secured to the inboard end of the lift platform, which barrier is actuated by a link to variously raise the barrier to a safety position and lower it to a bridging position in accordance with the position of the platform. The dual function barrier/bridgeplate system is particularly useful in combination with a parallelogram type lift employing an articulated lever assembly having a sliding block for leveraging the platform from a horizontal transfer orientation to a vertical, or over-vertical stowage position. There is disclosed a barrier assembly in which a spring assist system comprising a gas spring acting on one member of the articulated lever assembly and a lever arm linking a second arm of the articulated lever assembly to the barrier co-operate to actuate the barrier from a raised position when the platform is away from the transfer level and a lowered position to act as a bridge plate at the transfer level. A telescoping push arm is included which actuates the barrier by means of a pivoted link which rotates the barrier in response to the telescoping motion of the push arm. A safety interlock and load detecting system may be employed to prevent the platform from moving to the stowed position when a load greater than a predetermined weight is on the platform. An anti-free fall mechanism is disclosed comprising a pin in the slide block which engages mating slots in the telescoping push arm members to lock their length during the initial stage of deploy of the platform downwardly from the vertical stowed position.
